Description

Flow-disturbing band processing technology
Technical field
The invention belongs to heat exchange equipment technical fields.
Background technology
Pipe heat exchanger, it is most typical dividing wall type heat exchanger, its application industrially has long history, and And still leading position is occupied in all heat exchangers so far.Pipe heat exchanger mainly has housing, tube bank, tube sheet and envelope first class sections Composition, how rounded housing is, and inside is fixed on equipped with parallel tube bank, tube bank both ends on end plate.Spiral shell is rotatably connected in tube bank Knob band (also known as twist iron, flow-disturbing band, twisted flat bar etc.), spiral band are mainly used for improving heat exchanger effectiveness.When fluid into When entering in heat exchanger tube, spiral band causes so that fluid enters turbulent condition, breaks tube wall retention layer, increases fluid and heat exchange The contact area (improving heat exchange efficiency) of tube wall, and disorderly fluid can wash away tube wall dirt.
The process equipment of existing spiral band includes roller machine, bead cutter, fixing roller, apparatus for baking, circumgyration stretch dress It puts, automatic gas cutting machine, air cooling equipment etc., stalloy material is delivered to bead cutter from roller machine during processing, and thin steel is cut by bead cutter Meet the sheet material of Rack, sheet material enters apparatus for baking after fixing roller, sheet material is heat-treated, through Overheating Treatment Sheet material forms spiral knob using circumgyration stretch device (i.e. sheet material one end is fixed, and the other end is driven by circumgyration stretch device to be rotated) Band cuts off (spiral band for being cut into specific length) using automatic gas cutting machine and is cooled down by air cooling equipment sizing.
This spiral band processing technology the shortcomings that be:1st, when circumgyration stretch device drives rotation, the screw pitch of sheet material Being formed is influenced by factors such as circumgyration stretch device rotary speed, turn secondary, sheet material conveying speeds, several spiral shells of finally formed spiral band It is not exactly the same away from (being functionally equivalent to flow-disturbing unit hereafter), after such spiral band is mounted in tube bank, tube bank The flow-disturbing dynamics that interior different location fluid is subject to is different, causes to exchange heat uneven;Or the setting of circumgyration stretch device is unreasonable, turns It can cause that sheet material is twisted into two parts when secondary excessive;2nd, cut off spiral band when, automatic gas cutting machine along spiral band cross-sectional direction into To cutter, cutter is easily destroyed the spiral-shaped of spiral band, causes waste product.
Invention content
The invention is intended to provide it is a kind of ensure flow-disturbing element length it is identical, cut-out when will not destroy flow-disturbing cell configuration Flow-disturbing band processing technology.
Flow-disturbing band processing technology, includes the following steps:
A) cutting edge is handled:Sheet transport to trimming mechanism, the first cutting wheel, the second cutting wheel is cut along sheet length direction Sheet material forms the sheet material for meeting Rack;
B) the pre-heat treatment:Sheet material passes through heat treatment mechanism, and sheet material is worn along heating gap between upper heat conduction roller and lower heat conduction roller It crosses, sheet material above and below contacts respectively with upper heat conduction roller, lower heat conduction roller, and sheet material is heated;
C) crush-cutting sheet material prewire:Sheet material is extended downwardly using prewire cutting mechanism, the output shaft of telescopic cylinder, the One cutting knife, the second cutting knife, third cutting knife, the 4th cutting knife crush-cutting on sheet material go out 4 articles of prewires, and several prewires will Sheet material is divided into the flow-disturbing unit of several interconnections, and after the completion of crush-cutting, the output shaft of telescopic cylinder bounces back upwards;
D) torsion is handled:The flow-disturbing unit of sheet material is penetrated in the groove on the inside of grip block, and driving gear rotates counterclockwise 30 °, then driven gear is driven to rotate, driven gear then drives grip block to rotate, and grip block drives flow-disturbing unit to rotate counterclockwise, The flow-disturbing unit reverses;Flow-disturbing unit moves on, and after the flow-disturbing unit completely disengages groove, driving gear turns clockwise It is dynamic, driven gear is driven to set back;
E) turn-back is handled:Next flow-disturbing unit of sheet material is penetrated in groove, and driving gear rotates clockwise 30 °, So that the flow-disturbing unit torsional direction is opposite with upper flow-disturbing unit torsional direction;It so repeats, ultimately forms each flow-disturbing The flow-disturbing band that unit reverses, the twisting of adjacent flow-disturbing unit is opposite;
F) air-cooling moulding:For flow-disturbing band using forced air cooled tube, it is cold formed that the cold wind in forced air cooled tube brings sector-style into flow-disturbing;
G) it cuts eventually:It is cut along two prewire A directions being located on same wide line of flow-disturbing band, so as to complete flow-disturbing The segment of band, the flow-disturbing strip length after segment are the flow-disturbing band of specific length.
Advantageous effect:Actuating unit control cutting knife moves down crush-cutting sheet material and forms prewire, due to two sanctions in same group Cutter is not in contact with each other, so not connected with group two cutting knife crush-cuttings, two prewires, in addition, cutting knife is conveyed with sheet material Direction is vertical, is located along the same line with two prewires that two cutting knife crush-cuttings in group go out and hangs down with sheet material conveying direction Directly;And the length of the distance between the prewire of two groups of cutting knife crush-cuttings out as flow-disturbing unit, each flow-disturbing unit packet Include 4 prewires.The groove of grip block blocks the edge of the flow-disturbing unit of sheet material, gear mechanism (i.e. driving gear and driven tooth Take turns overall structure) drive grip block rotation so that and flow-disturbing unit reverses.
First, this programme using prewire come the length of specification flow-disturbing unit, the flow-disturbing element length of finished product flow-disturbing band It is identical, after flow-disturbing band is mounted on tube bank so that the flow-disturbing dynamics that the fluid of different location is subject in tube bank is identical, and heat exchange is more equal It is even;Secondly, this programme eliminates traditional circumgyration stretch device, and sheet material caused by traditional circumgyration stretch mode occurs is avoided to be turned round Disconnected situation, this programme are limited and are reversed to flow-disturbing unit using grip block, and the torsion of single flow-disturbing unit does not influence piece Remaining position of material can control windup-degree and the torsion side of flow-disturbing unit by the motion mode for controlling gear mechanism To;Again, due to foring section during crush-cutting sheet material prewire, the surface area of final sheet material entirety increases so that after molding Flow-disturbing band is when by air cooling mechanism, the contact area bigger with cold wind, improves the cooling effect of flow-disturbing band;Finally, most Egress break flow-disturbing band when, cut at prewire using manual or automatic cutting machine, due to the connection of adjacent flow-disturbing unit Portion is relatively narrow, and cutting workload is smaller, and the efficiency of cutting also improves a lot, and will not in cutting process compared to traditional mode Destroy the shape of flow-disturbing unit.
